The American West as you've never seen it before: Amazing 19th century pictures show the landscape as it was chartered for the first time. These remarkable 19th century sepia-tinted pictures show the American West as you have never seen it before - as it was charted for the first time.

The photos, by Timothy O'Sullivan, are the first ever taken of the rocky and barren landscape. At the time federal government officials were travelling across Arizona, Nevada, Utah and the rest of the west as they sought to uncover the land's untapped natural resources. Timothy O'Sullivan, who used a box camera, worked with the Government teams as they explored the land. He had earlier covered the U.S. Civil War and was one of the most famous photographers of the 19th century. He also took pictures of the Native American population for the first time as a team of artists, photographers, scientists and soldiers explored the land in the 1860s and 1870s. The images of the landscape were remarkable - because the majority of people at the time would not have known they were there or have ever had a chance to see it for themselves.
